On the Study for Free vibration of the CFRTP composite plate printed by 3D-printer

Abstract

Free vibration characteristics of the CFRTP rectangular plate printed by 3D-printer is studied in this paper. A CFRTP composite rectangular plate has been printed by a 3D-printer such as the Mark-Forged Mark Two printer. The vibration characteristics are measured by impulse vibration test, and then experimental modal analysis detects the natural frequencies, modal dumping ratios and natural vibration mode shapes. The numerical analysis is also carried out by using a commercial FEA software, ANSYS, to check the vibration characteristics of the plate obtained experimentally by impulsive vibration test.
